2018年5月18日 · VAV boxes control the volume of heated or cooled air entering a space in order to manage temperature, humidity, and ventilation. The boxes are calibrated dampers that use a butterfly/blade device to regulate airflow into a space. VAV boxes function fine in thousands of buildings around the world.

Venturi valves are devices designed to control airflow for room pressurization and fume hood air containment. They are most often used in spaces that require precise and accurate airflow control, protecting occupants from hazardous airborne gases and …

2018年9月20日 · To ensure safe air in their facilities, more lab designers and owners are specifying venturi airflow valves as an alternative to traditional VAV boxes. Manufactured by several companies, venturi valves are tubes with a constricted neck, resulting in a shape like an hourglass (Figure 3).

GOLO valve allows lab workers to more effectively control ventilation over a wide range of airflows - they can now match the ventilation rate to the risk of hazard. This also helps labs achieve their net zero goals.

What is a venturi valve? A venturi valve is a variable air volume control device, but operates differently, and more efficiently, than a traditional VAV terminal box. VAV boxes utilize dampers, which use a butterfly/blade device to regulate the airflow and volume of heated or cooled air.

Optimal for compact applications requiring tight geometries and smaller duct sizes like cage racks, cabinet exhausts, modular cleanrooms, and patient rooms, the 6-inch venturi valve provides accurate airflow control.

Triatek Venturi valves utilize fast-acting electric actuators that provide a rapid response to changing conditions. This rapid response ensures the airflow is maintained which is critical in areas requiring a specific threshold of air flow in order to protect individuals from airborne chemicals or particulates.

Trusted by the top hospitals, universities, and research facilities, Triatek Venturi valves help protect occupants from dangerous airborne pathogens, dusts and chemicals. Triatek Venturi valves are pressure-independent and maintain the desired airflow requirements regardless of …

Available in constant or variable air volume configurations, the Venturi Valve is able to control flow without the need for airflow measuring devices in the airstream. The device eliminates the possibility of lint or other airborne particulates interfering with the control or accuracy of the valve.

Constant airflow can be maintained in critical parts of the CAV system by applying EB Venturi Air Valve with pressure-dependent capability. Actuators, Controllers can be ideally programmed to maintain the required set point operating condition.
